Which setup is best? 5D II or 5D III?

So, I'm planning on either buying a completely new video setup this summer (well, after the summer once I have earned the money that I need), and I can't decide whether to buy a 5D II or III. I might even keep my GH2.

But basically, I cannot afford to spend more than $10,000 (I'd like to spend way, way less actually). If I get the 5D III, I need to sacrifice the L series glass that I was going to buy for the camera and get medium quality Canon lenses. If I get the Mark II, I'd be getting three L lenses instead of just one.

Here's my theoretical setup for the Mark II and III - which do you think would be the better choice?
